ast why they don't work for me)
Deb,
The standard eye glass lense and a magnifying lense are about the same
in shape. The outside surfaces are curved out so the lense is thicker in
the center than along the edges. They work for people who don't have
nearsighted vision. But for nearsighted people - well, they require a
lense that is ground to a convex shape. That is the outside of the lense
is ground so that the center of the lens is thin and the edges are thick.
Your natural lense is like that magnifying lense. Only to focus the
magnifying lense - you move it back and forth until you have it focused.
But the lense in yoyr eye cannot move back and forth, so the eye does
this little trick. A muscle ring around the lense squeezes or relaxes
and this changes the thickness of the lense - and it is this action that
allows you to focus on near or far objects. But in life, the lenses in
our eyes begin to hardens, and the muscles can't squeeze hard enough to
flex the lense, so we get tired eyes really quickly doing close up work.
Then in time, we lose the ability to do that muscle squeeze altogether.
At that point, we have to get glasses that change the angle the light
goes though our lense to focus in the right spot on our retina. In the
case of nearsighted people the distance of the lense from the retina
results in an image out of focus. The glasses take care of the problem.
In the case of farsighted people, they can't focus on closeup stuff, so
they have to have a different lens.
In time, many people like myself, will have to have cataract surgery.
The most common reason for this is yellowing of the lens which reduces
the amount of light getting into the eye. When this happens, we usually
always seem to struggle to get the light just right, or a brighter
light, but the real problem is the yellowing reduces the light passing
through.The common solution - in fact the only solution that I know of -
is the cataract surgery whereby they remove your natural lens and put in
a clear plastic one. I have had this done on both eyes, and believe you
me, I was astonished at how bright and vibrant colors actually were. I
had no idea how bad it had really gotten.
Another thing. I was near sighted all my life. Had to wear glasses to
see distant. With the new lens I now have 20-20 distant vision. I no
longer wear glasses at all for most things. I cannot tell you how
wonderful it is to be able to be out in weather fishing or something and
not have to be bothered with water on my glasses. I do wear reading
glasses for up close reading, but they are the kind you can buy for
$6-$10 at Walmart.
And finally - great advances are being made the area of cataract
surgery. There were more than a million cataract operations last year.
It is THE most successful operation in medicine today. One advance over
my surgery is the new lenses being put into use. My lens are fixed
focus, meaning I have to wear reading glasses to get things into focus
closeup. But the new lenses are active focusing lenses. One the new lens
is installed, the muscle ring works against two tabs on the new lens,
and this causes the lense to move back and fourth just like the lens of
a camera. So people who get new lenses installed today - can see as if
they have fully focusing natural lenses. This is a great advance. You
can have worn glasses always, and yet walk away from cataract surgery
and likely never have to wear glasses again.
I hope things worked out for you.

Hay Folks & Deb,
A bunch of years ago I needed new bifocals and my brother-in-law Joe told =
me about a lens that had the same prescription for 2' on the top and bottom=
of the lens with the distance in the middle. I guess they call them Double=
-D lenses, or carpenter's or mechanics lenses, and once you get use to just=
lifting your eyes to see the monitor and dropping them to type there is no=
more careening the neck back to see up close above brow level. Once in a w=
hile you might get into a position where you can't see good but that just h=
appens. I found they are great for cutting in painting along the ceiling an=
d wall line or crawling under the van to change the oil, anything close up =
and above my nose. They usually cost about $60-90 more per lens but they ha=
ve made many jobs a lot easier so, short of cataract surgery, these glasses=
have been well worth the investment.

ast why they don't work for me)
I had cataract surgery a couple months ago and got the fixed distance
lens. So I went from needing glasses for distance but seeing just fine
up close without glasses. Now it's the opposite. I need cheaters for
reading knitting, cooking, using the computer, grocery shopping, etc.
and the strength I need depends on the light and what I'm trying to do.
So I have cheaters scattered all over the house and often walk around
with both cheaters and sunglasses tucked in my Tshirt neck. It's taking
me a while to change my habits. I'm so used to just bringing things
closer to see them better, and now that doesn't work. On the other
hand, I can drive without prescription glasses and going down stairs is
easier.

I'm Posting this for Heather Edwards - if anyone is or has used the
kind of glaze she is looking for would they contact her directly.
Heather Edwards
Hello,
I am in the need of a cone 10 - 11 reduction bright green glaze and
was wondering if you would have any that I could try. I have
received a large commission for carved mugs in a leaf pattern and
the city would like them to be as bright a green as possible. I
fire cone 10 -11 reduction and work with B-Mix. At the moment I do
not work with a green at all, but this order will probably be
ongoing and quite lucrative. It would need to be transparent to
translucent for the glaze to break nicely in the carving.
I would appreciate any direction that you could give me. I prefer
not to work with any barium in my studio.
Thank you for your time.

I am very far sighted ... will walk into walls without glasses but
can see pretty well up close with no glasses... but middle
distance ( computer etc ) is a problem as well... I used
to do regular bifocals but found myself having to crane my neck up
to look at the computer and with as much time as I spend on it,
I would get stiff necks a lot... so the last time I got glasses,
I had them do two pairs: one was a normal pair of bifocals...
mostly distance with the small mid- range focus at
the bottom... and one pair for the computer... I had them do just
a small space at the top for distance ( so I could see out when
I looked up ) but with the major part of the lens the mid-focus
for the computer .. .. ( sort of reverse bifocals...with
the smaller part of the bifocal at the top instead of the bottom
It took me a while to convince them thats what I wanted.. but
eventually , they did it..and it works great ... no
more neck craning for the computer...

Almost invariably when I sit down at someone else's computer I get
this neck strain that Marci and others are addressing.
But sitting at my own computer, my chin is slightly down, my neck
relaxed, and I'm comfortable. My glasses are vanilla progressives,
essentially tri-focals, and I'm looking through the middle-distance
area of the lenses.
How? Taa dahh! LOWER the monitor--duh! (And if necessary, raise your sea=
t)
I have never understood why people position monitors so high. Or
why, when computers first came out they were always displayed with
their monitors sitting atop the computer case (laid flat), thus
raising the monitor another 8 inches or so above the desk top.
Now that most all monitors are flat panel and have adjustable height,
just push 'em all the way down. Mine is less than an inch above my
(standard height) desk top.

When computers first had display screens, the
prevailing idea in ergonomics was that you should
always work with your head up, facing straight ahead.
This is now thoroughly debunked. In fact, the most
natural and strain-free head posture is slightly
downward. Newer monitors sit lower, but since
they are placed on standard-height desks, (perfect
height for work done ON the desk surface) they are
still too high. A lower desk helps a lot.
